The evolution of photosynthesis and its associated metabolic pathways has been crucial to the successful establishment of plants, but has also challenged plant cells in the form of production of reactive oxygen species (ROS). Intriguingly, multiple forms of ROS are generated in virtually every plant cell compartment through diverse pathways. As a result, a sophisticated network of ROS detoxification and signaling that is simultaneously tailored to individual organelles and safeguards the entire cell is necessary. Here we take an organelle-centric view on the principal sources and sinks of ROS across the plant cell and provide insights into the ROS-induced organelle to nucleus retrograde signaling pathways needed for operational readjustments during environmental stresses.
光合作用及其相关代谢途径的进化对植物的成功建立至关重要,但也以活性氧(ROS)产生的形式挑战了植物细胞。有趣的是,通过不同的途径,几乎在每个植物细胞隔室中都会产生多种形式的 ROS。因此,需要一种复杂的 ROS 解毒和信号网络,该网络同时针对各个细胞器进行定制,并保护整个细胞。在这里,我们从细胞器为中心的角度来看待植物细胞中 ROS 的主要来源和汇,并深入了解 ROS 诱导的细胞器到核逆行信号通路,这些通路在环境胁迫期间进行操作调整时是必需的。
